Cinereous-breasted Spinetail

Identificazione

The cinereous-breasted spinetail is 15 to 16 cm (5.9 to 6.3 in) long and weighs 15 to 18 g (0.53 to 0.63 oz). The sexes have the same plumage. Adults have a faint gray supercilium on an otherwise gray-brown face. Their forecrown is dark gray-brown, their crown and nape chestnut-rufous, and their back, rump and uppertail coverts dark brown. Their wing coverts are chestnut-rufous and their flight feathers dark brown with rufescent edges. Their tail is a darker brown than the back; it is graduated and the feathers have rounded tips. Their chin and throat are mostly whitish; the lower throat feathers are blackish with whitish edges. Their breast is brownish gray ("cinereous" means ash-colored), their belly whitish, and their flanks and undertail coverts brownish. Their iris is reddish brown, their maxilla black, their mandible silvery gray to grayish horn, and their legs and feet olive or grayish olive to brownish yellow. Juveniles have a gray-brown crown, mostly ochraceous clay-brown underparts, and a less distinct throat patch than the nominate.

Areale e habitat

The cinereous-breasted spinetail has a disjunct distribution. One population is found in far eastern Peru's Department of Madre de Dios, northern and eastern Bolivia, and Brazil's western Amazon Basin. Another is found from Ceará and Alagoas in northeastern Brazil southwest through Mato Grosso do Sul slightly into southeastern Bolivia and northeastern Paraguay. There are also records at scattered locations throughout central Peru, but some of these are suspected to be misidentifications. <p>The cinereous-breasted spinetail inhabits a variety of open landscapes including seasonally wet grassland, scrublands, campina, and savannah. Within them it favors areas near water. In elevation it ranges from near sea level to about 700 m (2,300 ft).
